Another Suggestion is to add in the ability for NPC, cities or rouge, to be able to forge allainces, even making kingdoms. This would add another for for players to either take on or ally with. For the evil NPCs that combine, they can start attacking other players, making them forge a alliance to defend themselves. If they get strong enough, there can even be a event where they declare a World War against the players, making the game much more interesting. Thank you for your time to read this.
